i can't really say that i'm a massive Slayer fan, but I have heard part of 'Raining Blood' and i really enjoyed it. unfortunately, i haven't really had the time to properly listen to it...:sad: hopefully i'll get to know it soon though!!!

I'd go with Raining Blood closely followed by Bloodline. First time I even heard of Slayer was from VRock (a radio station in GTA : Vice City), in which Raining Blood was their one and only featured song. I then found Bloodline, a song that just instantly clicked with me.
